The box illustrated in the drawings consists of a body and a wingextending outwardly therefrom and arranged to form a bight therebetween.The box is constructed from a substantially rectangular blank havingtwo' longitudinally extending scores spaced from the lateral edges ofthe blank to provide alongitudinal intermediate portion and na'rgin'alportions issuing therefrom. InLadditi'on; the 'blanlc is formed with anumber of transverse scoresv dividing the intermediate portion intopanels .forming 2when erected a: top Wall and an outer end wall for.the: wing; Further, transverse scores provide on the intermediate"portion panels forming when erected a rear. end wall, a top wall andinner end wall for the body,

and a bottom wall common to both the wing and the.

body. The blank extends outwardly beyond the inner.-

end. wall panel for the body and'is severed along a line.

- two angle shapedwall structures issuing from the lateral edges of the'inner end wall panel of the body and flaps fold-able inwardly from theoutermost edges of the same. These wall structures provide legs whichwhen the box iserected; formthe lateralwalls of the body and other legs:which extend into thesame and engage the top wall of the wing and thebottom wall of the box. The blankis further formed withscores extendingacross the marginal portions: of the same and provide panels:

which when erected form the lateral Walls of the box said walls beingadapted to overlie the portions of the lateraliwall structures-of thebodyand close the sides of the wing; The inner endwall of the body isformed, with a shoulder and the top wall ofthe wing is formed with=atongue engageable with said shoulder when thebox is closed to hold theparts in assembled relation. A band of adhesive tapemay be used whichextends about the wing and engages the flaps, top wall and bottom wallthereofand further holds the. parts from disengagement.

The. improved box as illustrated in Fig; 1 is indicated by the;reference character A, and consists of two portions B and C. Portion Bis referred to as the body of the box 'and'portion as a, wing issuingoutwardly there-- from. This body serves the purpose of receiving anarti cleD such as shown in Fig- 3. The body B andthe wing C aresoconst'ruct'ed that when the box is assembled a:

Bight 20 is formed between said portions of. the box.

The article ID, as best shewn in Fig. 3, consists of av case 10rectangular in form and which. has issuing from iti'a tubularprojecting-member 11. This member issues from" the top' 12' of thecasefand near one ofv the sides 13 theretifi The article has otheradditional parts whichmay' be suitably supported in the box. Theinvention proper" con'cerns itself principally with the attachmentofitlie closure members of'the body and wing, and has no particularreference to these parts. Said parts have h'ence not been illustrated ordescribed in detail in the application. r

The box A is constructed from a single blank 14 which issubstantiallyrectangular in form and which has twov longitudinal scores 15 and 16.These scores are spaced from the lateral edges of the blank and dividethe blank into rn'a' rgi'nalportions 17 and 1'8 and a longitudinalintermediate' p'ortion' 19. Extending across the intermediate portion 19are a n-urnber of scores 21, 22, 23, 24 and which divide theintermediate portion into panels which when erected form a top wall '26,an outer end wall 27 for the wing C, a bottom wall 29 common to both thewing and the body, a rear end Wall 30, a top wall 31 and an inner endwall 32 for the body B.

' Tlrese form in combination an intermediate longitudinal wall structurefor the box. The blank is further formed with transverse scores 34 and35 extending in substantial alignment with the scores 23 and 24 andwhich form in the marginal portions 17 and 18 angleshaped flaps 36issuing outwardly of the bottom wall 29. The marginal portions 17 and 18are formed with kerfs 38 and 39 which, together with the scores 34 and35, form flaps 41 issuing from the flaps 36 and which, when the box iserected, are adapted to lie within the box and adjacent to the outer endwall 27 of the wing and the outer end wall 30 of the body. The flaps 36and 41 are formed with extensions 66, the upper edges 67 of which engagethe top wall 31 of the box when erected and stifien and reinforce thebox. The kerfs 39, together with the scores 15 and 16, form on the topwall 26 other flaps 42 which issue outwardly from the top wall 26 andwhich, when the box is erected, are adapted to be received within theflaps 36 to form lateral walls for the wing C.

The blank 14 is provided with a projecting portion 43 which liesoutwardly of the panel forming end inner wall 32 of the body B. Theblank is formed with scores 44 which extend across the marginal portions17 and 18 of the blank and in substantial alignment with the score 21.In addition, the blank is formed with a transverse kerf 45 separatingthe projecting portion 43 from the intermediate portion 19 and providingin the panel forming the inner end wall 32 an inwardly facing shoulder46 which serves a purpose to be presently described. The projectingportion 43 is further constructed with a longitudinal kerf 47 which issituated midway between the scores 15 and 16. In addition, the blank isformed with longitudinal kerfs 48 which define the lateral edges of thepanel forming the top wall 31 of body B. By means of this construction,two angle shaped lateral wall structures 51 and 52 are provided whichhave legs 53 and 54. The kerfs 48 and the scores 44 form flaps 55issuing from the legs 54 and which are separated from the remainingparts of the marginal portions 17 and 18 along lines 56. V

In mounting the articles D within the box, the case is received withinthe body B of the box and the projecting member 11 is received withinthe wing C. When the box is placed on the bottom 29 and the articleinserted into the box, the projecting member 11 lies horizontally asshown in Fig. 7 and extends into the wing C, the side 13 of the articleresting upon the bottom wall 29.

The box is so designed that the shoulder 46 on the inner end wall 32 andformed by the kerf 45 lies flush with the top wall 26 of the box whenthe same is in erected position as shown in Fig. 4. Formed on the end ofthe top wall 26 of Wing C is a tongue 58 which engages beneath theshoulder 46 when the box is closed. The width of the legs 54 issubstantially equal to the height of the flaps 42 so that when the boxis erected these legs are received within the flaps 42 and engage thetop wall 26 of wing C and the bottom wall 29 of the box. When the tongue58 is disposed beneath the shoulder 46, the parts become locked inposition. This construction provides a space 59 which brings thecompartment 61 within the wing C into communication with the compartment62 within the body B and through which the projecting member 11 of thearticle D extends.

The method of assembling the box and of inserting the article in the boxis as follows: The lateral wall structures 51 and 52 are first foldedalong the scores 44 to cause the flaps 55 to project angularlytherefrom. The inner end wall 32 is next folded along the score 21 andthe lateral wall structures 51 and 52 folded along the scores and 16.The parts then become arranged as shown in Fig. 5 with flaps 55overlying the top wall 31. The flaps 41 are next folded along the scores34 and 35 and the flaps 36 and 42 folded along scores 15 and 16, theparts taking the positions shown in Fig. 5. The outer end wall 27 ofwing C is next folded along score 24 and the outer end wall 30 of body Bis folded along score 23 until the parts take the position shown in Fig.6. The article D is next placed within the box in the position shown inFigs. 4 and 7. The wall structures 51 and 52 are now caused to enterinto the box with the edges 63 of the same resting upon the bottom wall29 of the box. This causes the parts to assume the position shown inFig. 7, completing the formation of the body B. When the parts are soarranged, the legs 54 together with the extensions 66 and flaps 36 formthe lateral walls of the body B while the legs 53 lie along the innersurfaces of the flaps 36. Also the upper edges 67 of the flaps 66 and 36engage the top wall 31 of the body B. The top wall 26 of the wing C maynow be folded into position. In the folding of the same, the flaps 42may be inserted between the legs 53 of the wall structures 51 and 52 andthe flaps 36 or inwardly thereof as found desirable. In either case, asthe tongue 58 reaches the crotch of the bight 20, the same passesbeneath the shoulder 46 on the inner end wall 32 of body B and togetherwith the legs 53 lock the parts in position. The operation of packagingthe articles is completed by wrapping a band of adhesive, not shown,material about the wing C if desired, thus securing the various walls ofthe wing from movement and holding the parts rigidly assembled. Theadvantages of the invention are manifest. A very strong construction isformed at the bight between the body and wing of the box which rigidlysupports the article within the box and prevents separation of the wingfrom the body in the transportation and handling of the box. The addedstructure is formed from portions of the blank without waste ofmaterial. With the instant invention, stapling of the parts together isdispensed with and the box held closed by the interlocking of the parts.The box can be quickly and easily erected thus saving time in thepackaging of the goods.
